ADJUSTABLE 'j WRENCH.

Appucation filed July 21, 192s. seal No. 124,036.

An object of this invention is the provision of a simply constructed, quickly oper'- ated wrench'. I

A further object is the provision of a wrench including a stationary jaw having a shank which merges 1n a handle, and a movable jaw which isslidable on the shank, andy in which means arranged for slidable movement on the shank and handle operate mechanism for moving the slidable aw toward or away from the fixedv jaw, whereby the jaws may be quickly adjusted to engage with or to release an art-icle therebetween, and further wherein the construction is such that any play or tendency of movement of the slidable jaw with respect to the stationary jaw will be 'effectively prevented.

To the attainment of the above broadly stated objects and many others whichV will present themselves as the nature -of the invention is better understood, the improvement resides in certain novel features of construction, comb-ination and operative associ-` ation of parts, a satisfactory embodiment of which is disclosed by the accompanying drawings.

In the drawings: Fig. 1 is a side elevation of a wrench in accordance with this invention, there being parts in section;

Fig. 2 is a similar view looking towardV the opposite side of the wrench and showing the slidable jaw moved against the stationary jaw;

Fig. 3 is a sectional view on the line 3-3 of Fig. 1;

Fig. 4 is a sectional view on the line .4--4 of Fig. 1;

Fig. 5 is a sectional view on the line 5-5 of Fig. 1; Y

Fig. G is a sectionalfview on the line 6-6 of Fig. 1; and l Fig. 7 is a face view of the rack-bar.

My improved wrench is preferably wholly` constructed of metal and includes a stationary jaw having an angle shank 2. The shank is of a. lengthwhereby the outerend thereof provides a handle, and for distinction the handle part of the shank is indicated by the numeral 3.

The handle 3 is centrally longitudinally slotted, as at 4, andthe shank, from its juncture with the jaw 1, is centrally formed with a web 5 which has a widened part 6. The enter wall of the widened part ofthe web bridges the slot 4 of the handle, 'and ings.

- nects the heads 19 and18.,

.milled or rounded.

by thus widening the web the same is thickcned and the said thickened portion is provided with'an elongated longitudinal pocket 7. The wall and the inner side of the web v5 is of a less length Vthan the outer wall or part 6, and arranged below the end of what I termA the inner wall of the web, there is a toothed wheel 8 that is fixed on a shaft 9 that is journaled transversely through the shank. Suitable means is, ofcourse, provided for holding the shaft 9 from longitudinal movement. On one end of the shaft, outwardly with respect to the shank 2 there is fixed a beveled gear 10, and this gear is in mesh with a beveled pinion 11 that is fixed on one end of the non-threaded or shank portion12 of a screw-13. The shaft portion of the screw is journaled in a bearing opening in a lug 14 vformed on the end of a yoke member which straddles and which is fixed,

as at 16, to the sides of the shank 2. The

' screw 13 is received in the threaded bore 14:

on the body or carriage 15 of the movable jaw 1.6 of the improvement.

" Guided in the pocket 7 there is a rack bar Y 17 with which the teeth of the wheel 8 engage; The lowervor outer end of thev rack bar is widened `or thickened, as at 18, and the sides of the said thickened or widened portion 18 of the rack bar 17 are widened as clearlydisclosed by Figure 7 `of the draw- By this arrangement it will be seen that the bar 17 is received in the slot 4 while the widened or head portion 18 thereof contacts with the handle at the opposite sides of the said slot. The head 18 has its outer face milled. A second head member 19,hav ing a central .reduced portion or web 20, is also provided, and the web 20 is received in the slot 4 at the opposite side thereof from ythat on which the head 18 is arranged. A

removable and adjustable element 21 conof the slidehle jaw toward or may from the movable jaw, So that when en article is gripped between the jews e, firm bite on suoli urtiele is ineui'ed. The uotye `fuofes the juive maiybe concered :ind toothed so that the wrench een be employed 4upon both nuts and pipes. |The iinpi'oveii'ient is oompurutively simple und the jews muy eaeily and quickly adjusted With the minimum amount of physicaly exertion upon the part 'of the operator. `The i)inpioven'ient, is, ,ot course, `not to be restricted to the precise *deytuile herein set forth as -hold niyeelfen titled to .euch changes therefrom iasr fairly {full Within the Scope what I claim. o Having deecribedvthe inyentioinleleinzl.
